Indemnification Costs in the Dam Safety Decision
The ASCE Task Committee on Spillway Design Floods has proposed safety criteria for three categories of dams. Category 1 dams are those with anticipated failure consequences so large and...

The GEV Distribution in Drought Frequency Analysis
Three decades have passed since A. F. Jenkinson found the general solution to the Stability Postulate, which is the condition that all the extremes must meet, and after him that solution...

A Flood Prediction Geographic Information System
The paper discusses a GIS that derives kinematic wave model parameters using stream network, elevation, and basin boundary data. Various approaches are being investigated for estimating...

Muskingum Flow Routing Using Personal Computers
The paper discusses how tedious computations involved in flow routing can be easily implemented on Personal Computers. Parameter estimation and routing calculations for both linear and...

A Filtering Approach to Flood Routing
Hydrologic river routing and hydraulic channel routing are in general use for flood routing. Both approaches use deterministic mathematical models and treat inflow and outflow hydrographs...

Safety Design Flood for Too Wide Creek Dam
This paper presents an example application of the procedure developed by the ASCE Task Committee on Spillway Design Floods for a dam on the Too Wide Creek. The example was developed from...

Development, Use, and Synthesis of S-Graphs
A study to identify S-graphs from the southwestern United States has been completed. This study has resulted in the compliation of 53 S-graphs, documentation of some of the watershed characteristics,...

Flood Hydrology Modeling: U.S. Virgin Islands
To develop a consistent basis for evaluating existing flooding problems and for planning activities to reduce future flood damage, a watershed modeling project was initiated by the Government...

Impact of Temperature on Columbia River Winter Floods
During the course of an extensive study of the Columbia River drainage to evaluate a major levee system near Portland Oregon, it was noted that flood runoff produced by winter storms with...

The Dallas Floodway Project
This paper explores the history of the Dallas Floodway project, past performance of the project under various flood conditions, recently updated hydrologic and hydraulic evaluations, and...

Probability Based Evaluation of Spillway Capacity
Spillway adequacy could be evaluated more objectively if estimates were available of the probabilities of discharges up to the Probable Maximum Flood (PMF). As a first step in making such...

Monte Carlo Approach to Spillway Design Floods
This paper shows the use of a daily stochastic streamflow model for the calculation of the hydrograph for spillway design. Most of the literature related to the topic deals with the problem...

An Analysis and Comparison of Probable Maximum Floods with 10,000-year Frequency Floods and Maximum Observed Floods for Spillway Design
The use of deterministic probable maximum floods are supported in part by the conclusions of an Interagency Work Group formed to address the following questions: (1) Is it within the state...

Paleoflood Studies in Colorado
Paleoflood hydrology is the study of botanic, sedimentologic and geomorphic flood evidence remaining in a valley. Paleoflood studies in the Colorado foothills and mountains have been used...

Criteria for Selecting a Reservoir Routing Method
Results of an investigation comparing dynamic and storage reservoir routing applied in dam safety analyses are presented. Outflow hydrographs computed by these reservoir routing methods...

Time Base of a Hydrograph
For design projects in water resources, a hydrograph is commonly used to determine the required flood volumes. The time base of a hydrograph is a crucial parameter in such studies, and...

Fault-Tolerant Design for Data Acquisition and Flood Forecast Systems
An innovative fault tolerant flood warning system is currently being installed in the Passaic River Basin. The new system is designed to automatically tolerate the failure of major components...

Engineering Hydrology
The Surface Water Hydrology Committee, ASCE Hydraulics Division, sponsored this first Symposium on Engineering Hydrology. The Symposium was held jointly with the ASCE National Conference...

Dam Safety Relating to Merwin and Yale Hydroelectric Projects
This paper describes the safety investigations performed to evaluate the dams, associated with the Merwin and Yale Hydroelectric Projects, for the effects of severe floods and earthquakes....

Study of River Stage Fluctuations Resulting from Possible Operations of the Susitna Hydroelectric Project
Operation of the project to follow load may result in discharge and river stage fluctuations which could affect habitats and fish food sources. Limitations on hourly, daily, and weekly...
